DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.

DNA, or deoxyribonucleic acid, is fundamental to your growth, reproduction, and health. Read about its basic function and structures.

4-Strand DNA Structure Found in Cells. A newly discovered unusual nucleic-acid structure might have a role in regulating some genes. By Alison Abbott & Nature magazine.

DNA or deoxyribonucleic acid is the basic hereditary material present in all the cells of an organism and basically provides a blue print for the cell’s functions, growth, reproduction and death.

The structure of DNA made visible Date: August 31, 2015 ... -- the very first direct image of a DNA strand with resolution 20 times better than that achieved by Di Fabrizio in 2012.

But a quite different, square-shaped type of DNA structure can easily be created in the laboratory by the folding of synthetic DNA strands rich in guanine, one of the building blocks of DNA.

The discovery builds upon the landmark 1953 breakthrough when Watson and Crick revealed DNA’s double-helix structure. For replication to occur, the helix must first unwind, splitting into two ...

Researchers discovered a previously unknown function of RNA, potentially opening the door to new ways to treat cancer and neurodegenerative diseases.

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of ...
